Background technology
World Auto Industry booming also brings oil consumption, safety and environmental protection while bringing convenience to people's lives
Three major issues.According to related data introduction, under normal circumstances, automotive dead weight often reduces 10%, and fuel consumption can reduce by 6%~8%,
Discharge reduces by 5%~6%.And fuel consumption often reduces 1 liter, CO2Discharge capacity reduces 2.45kg, is reducing oil consumption, energy saving
While also reduce the discharge capacity of carbon dioxide and other harmful substances, mitigate environmental pollution.At the same time, automobile loss of weight is also
Living load can be reduced, the driving performance and security performance of automobile can be improved, therefore automotive light weight technology has become the following vapour
The inexorable trend of vehicle development.
Body lightening is the important component of automotive light weight technology technical field, is automobile using lightweight body material
The effective way of body lightening.The ceramic phase reinforcement intensity of in-situ endogenic particle enhanced aluminum-based composite material is high, surface without
